To all whom it may concern.-

Be it known that I, DAVID STILL, a citizen of the-United States,residing at Milton, in the county of Umatilla and State of Oregon, haveinvented a new and useful Improvement in Portable Feeders forThreshing-Machines, of which the following is a specification.

My invention is in the nature of a portable I feeder for feeding tothreshing-machines grain which has been harvested by machines known asheaders c'. 6., grain which has been cut off just below the heads. Theseheads of grain as cut ofi by the headers are usually loaded loose intowagon-beds and are unloaded onto the feed-apron by means of nets, or ifthe grain has been cut and stacked derrick-forks are employed totransfer it to the feed-apron.

Y My invention comprises a portable wagonlike body mounted on wheels fortransportation, provided with longitudinal and transverse feed-apronsand picking and feeding devices, whereby the grain is fed to an elevatorleading to the feed-table of the thresher, the wagon-body being alsoprovided with a derrick to facilitate the loading of the grain into thesame and the feed-aprons of the device being connected by a suitablepower-trans mission shaft and universal joint to the power mechanism ofthe thresher.

By my invention much heavy work of distributing the grain in theelevator is avoided, the grain is fed fast or slow, as may be desired,and a great economy of time and labor is secured.

Figure 1 is a side elevation of my portable feeder with parts brokenaway. Fig. 2 is a plan view with parts broken away and showing thefeeder juxtaposed to the thresher and connected up with the same by thepowertransmission shaft and the elevator. Fig.3 is an end elevationtaken from the left-hand end of Fig. 2. Fig. 4 isa perspective view ofthe transmission-gears.

In the drawings, Fig. 1, A represents a wagon-like body having two highside-boards and one closed end. The closed end is shown on the right ofFig. 1, the other end being open for the purpose hereafter described;This wagon-body is mounted upon wheels A to permit it to be transportedin the field along with the thresher.

The bottom of the wagon-body is formed of an endless slatted apron B,traveling around transverse rollers O O, located at opposite ends of thewagon. The upper run of this slatted apron is sustained upon and travelsover small rollers b, so that it is able to sustain considerable weightwithout sagging down.

At the open end of the wagon-body the main longitudinal apron Bdischarges onto a smaller transverse apron F at a somewhat lower level,and this transverse apron F discharges into the lower end of an elevatorE, (see Figs. 2 and 3,) which leads up to and discharges onto thefeed-table of the thresher.

Mounted on the wagon-body is a detachable and folding derrick-frame D,which has on its horizontal bar at the top a supporting eye or hook (Zfor a sling or block and tackle, by which the receptacle containing thegrainheads is raised and the grain dumped into the wagon-body and on thetraveling and slatted apron, whose motion gradually feeds the grain ontothe elevator, the movement being regulated and under control, ashereafter described.

As the wheat or other grain is discharged from the longitudinal apron Bto the transverse apron F it is stirred and distributed uniformly bypickers H. These pickers consist of long bars arranged longitudinallywith the wagon and having on one end bent tines, like a rake orpotato-hoe, which project a short distance into the wagon and rake outthe grain from the longitudinal apron onto the transverse apron. Thesepickers are at their inner ends loosely mounted upon the bent portionsof a multiple crank-shaft J, whose rotation imparts to the pickers thenecessary movement.

On the outer side of the transverse apron there are a rear wall M and aside wall M, which hold the grain onto the transverse apron. Outside therear wall M and near its bottom there are pivoted a number of uprighttilting bars I, which at their upper ends are pivoted to the outer endsof the pickerbars H, the connection being made adjustable by a series ofholes in the tops of the tilting bars and a detachable pivot-bolt foreach. As the crank-axle J rotates the front end of the pickers are alsogiven a rotary raking movement, the tilting bars I moving back and forthon their lower pivots to accommodate such movement. By raising orlowering the connection of the picker-bars H with tilting bars I therake end of the pickers is made to approach more or less closely to thetraveling apron B.

The transverse apron F is distended about two rollers G G and is rotatedthrough the roller G.

I will now describe the means for driving the various'parts of myfeeder.

K, Figs. 2- and 3, is a transmissionshaft, which connects with a jack orsome other power connection of the thresher. This shaft to avoid thenecessity for accurate alinement is provided with any suitable form ofuniversal joint 16.

Referring now to Fig. 4, the transmissionshaft K near the wagon-feederis provided with three rigidly attached gear wheels. The middle gear Kis a bevel gear and meshes with a bevel-gear G on the prolonged end ofthe shaft of roller G, which latter drives the transverse apron F. Anouter gear K on the transmission-shaft meshes with a gear-wheel J on ashaft J which shaft has a rigid sprocket-wheel J and this sprocket-wheelis connected by a chain belt J 2 to a sprocket-wheel J on the crankshaftJ. This connection drives the multiple crank-shaft which operates thepickers. An inner gear K on the transmission-shaft K meshes with a gearC on a shaft C and this shaft C has a small friction-pulley G on top ofwhich at the will of the operator there rests a larger friction-pulleyC. This friction pulley is carried in bearings in a yoke-shaped frame 0,whose two legs are pivoted at c to the main frame of the machine. Theshaft C of the pulley C is provided with a rigidlyattachedsprocket-wheel G which through chain belt C is connected with asprocketwheel C ,fixed to the shaft of one of the main apron rollers C.This connection drives the main apron in the bottom of the wagon but itmay be interrupted at will, as follows: A hand-lever C is pivoted at itsend to an eye bolt or other connection in the main frame, and a link 0connects the hand-lever C to the adjustable frame C of pulley C. To stopor start the main apron B in the wagonbody, it is only necessary toraise or lower the pulley C out from or into contact with the subjacentpulley C. When the pulley O is raised, the transmission of power to themain apron B is interrupted, and when pulley C is lowered the apron B isagain started into motion. This is an important feature of advantage,since as the grain is dumped onto the main apron B in more or lessirregular lots it is necessary to have the discharge of the grain fromthe main apron B onto the cross-apron F under perfect control, so thatif there should be any tendency of the pickers on the elevator to becomeclogged the movement of the main apron may be instantly stopped untilthe congestion is relieved and the main apron started again whenever thecircumstances justify it. It will be understood that while the mainapron is thus stopped the pickers and transverse apron still continue inaction.

To prevent the grain from passing down at the edges of the apron,aninclined overhanging guard a is fixed to the side walls andoverhangsthe edges of the apron.

Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent, is-

1. A portable feeder for threshing machines, comprising a wagon-likebody having a slatted and endless longitudinal apron in its bottom, atransverse apron at the end thereof at a lower level, an externalpowertransmission shaft, drivinggears for connecting the same to the twoaprons and means for interrupting the transmission of power to thelongitudinal apron without affecting the movement of the other.
